Improvements in Vater-Elevating Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enableA others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to the letters 'and figures of reference marked thereon, which form a part of this specification.

My invention relates to improve-ments in apparatus for elevating water and consists in utilizing air compressed in a subterranean cavity, the top of whiclris located belogv the outlet for a source of water supply to the said cavity. lvhe water from the sou/ree passes downwardly through a pipe whose upper extremity'is immersed in the Water of the source and' whose lower extremity ,is immersed in the water of the sub-- terranean chamber, l projecting considerably below the top of the chamber, in order to leave an air space, while the lower extremity ot' the pipe is still submerged. The upper extremity oit' the said 'pipe is equipped with air tubes whose upper extremities are in cour munieation with the atmosphere, while their lower portions are submerged in the 'water o-f the source and equipped with yopen-ended tubes, whereby as the water passes downwardly through the pipe, air is drawn into the Water -and mingles therewith until it. reaches the subterranean cavity, when it separates from the water, rises in the upper part of the cavity and forces the water downwardly. lhe water is raised through a standpipe whose lower extremity is also submerged in the Water of the subterranean chamber and whose upper extremity terminates at the elevation to which it is desired to raise the water. The lower portion of this standpipe, at' some distance above the bottom thereof, is perforated so that when the water in the chamber is depressed, as the air pressure increases, sufficiently to uncover these perforations, the compressed an: will enter the standpipe and rise upwardly therein carrying the water with it7 to any desired l height.` .By virtue of the fact. that the air under pressure in the subterranean chamber, enters the staudpipe, and mingles with the water reducidoy the specific gravity oi the latter, it becomes practicable to advantaJ geously elevato water and other liquids by the use o't my improved apparatus.

llavinpr hrietly outlined my improved construction, I will proceed todeseribe the same companying drawing` in which is illustrated au embodiment thereof.

In this drawing: Figure l is a section cutting' a subterranean chamber showing the two pipes ot the apparatus in place. Fig. 2 is a sectional view of the upper part of one ot the downllow pipes shown on a larger scale. Fig'. 3 is a section of the lower extremity ot' the Istandpipe shown on a larger stalle.

The same reference. charac-.ters `indicate the same parts in all the views.

Let the numeral. 5 designate a downtlow pipe whose upper extremity is equipped with a framework (3. hiringr air tubes 7, whose extremities are always in conm'iuuieation with the atmosphere. The lower extremities ot these tubes are connected with the. outer edge 8 ot the. l)utwardly-tlared top ot the downtlow pipe 5. It may be stated that this upper portion t) of the downtiow pipe is separate from the body 10 of the pipe and inserted in the top thereof, being provided with a collar 11, secured. by a set bolt 12 and resting' on the top flange 13 ot' the body ot' the downow pipe. The tubes 7 are equipped below the water level 'lt with rela.- tively small pipes 15, which it may be assumed are always submerged in the water. (lcntrally mounted on the frame 6, is a screw sha'lt lo threaded in a central hub 17, mounted on the framework 6. tremity ot'- this shaft is provided with a hand wheel 1S, while its lower extremity is connected with a t'unnt-lshaped member 19, whose outer portion extends above the small air pipes l5. s shown in the drawing (See Fig. 2). this cone-shaped. member is located entirely below the water level ot the supply source. As the water tiows downwardly in detail. reference being; made to the ac-` The upper extlirougli tbe pipe 5, tiere is sutiieient suction to cause eir toenter tue upper extremities of the pipes 'Z enel pese out into the' water tl'irougb tbe smell tubes or pipes l5 e This air is cerrieol clownwerflly with tbe wer ter which enters the subterranean chamber 2U, .tills the latter and overliows through en u pwsrlly-entening outlet 2l, the seid ont' iet terminating above tlie top tbe subte? lo runeain ebmnber snol suiieiently below the level oit the o?? ipply to @ive nee essery bead i. pnrpf be bot'- tom or lower portion of tbe elomiriow pipe 5 is frustuin-sbepecl, b ing largest et its i5 lower extremity7 which is located Within tbe cbeinbei' 2lb The -stenflpipe bes its iewer extremity 'rustoeonioel nu "i ape, protriuiing into tbe chamber extenii D eonsitlereble 2G distance be iv tbe top of .v l The tunnelM neel portion of tbe iower extreinit use of my improvement, tbe parts censtitilting the apparatus are arranged, as shown in Fig. l.. in this event tbe water from e source :'28 of naturel supply, flows downwerdly through tlieeownfiow pipe 5, into the ebunber 20. As tbe chamber lille with water., whereby tbe lower extremities ofthe two pipes are submerged, air which is drown. i'i'om tbe atmosphere into this water, rises into tbe top of the chamber above the, wat lei enti being trapped, accumulates therein whereby it isvsubjeeteii to compression sind 'forces the water downwardly in the seid ebember until `the perforiitions 23 in tbe 59 lower extremity of the stenclpipe are uncovered. after which the en' enters these ope'n7v ings and is unclerfsutiieient pressure toeleyzite tbe water finti cause it to overiiow et tbe upper extremity of the stenclpipe.
